ABSTRACT

The invention provides a machine for the assembly of three strip materials into a multiple-layer packaging or wrapping material. A top layer strip is fed to a printing machine. An intermediate layer strip of, for example, metal foil is fed to a corrugation machine, and the corrugated layer is fed with a backing strip to a gumming machine which unites them. Then the printed layer and the united intermediate and backing layers are fed to a gumming machine which assembles them. The multiple-layer product can be fed to a cutter and divider.

Montonc Attorney-William Anthony Drucker PACKAGING PRODUCTION The invention consists of the construction of a helio printing device combined with machines making microcorrugations, rotary gummers and cutters making it possible to obtain protective packings ready for assembly from three layers of sheets of paper or other material of the same or different qualities.

It features the components used either taken together or separately, and in particular the combination of spool-holders with block and tackle gear and a guide feeding a helio printing machine with a dryer, while simultaneously two other feeders feed a machine making microcorrugations, the other a gummer so that the two assembled strips take the printed cladding fixed by gumming, while the strip is offered to a mu]- tiple-action automatic rotary cutter and to a divider'giving out the wrapping, flat, ready for assembly.

In the accompanying drawing, showing a nonlimiting example of the invention:

The device is shown diagrammatically as a whole, with the positioning of the components making up the combination.

The device comprises double spool-holders 1, 2 and 3 hearing the sheets for printing 4, for corrugation 5 and for backing 6.

The sheet 4 for printing passes over the assembly made up of three fixed upper cylinders 7, 8, 9 and two mobile cylinders l0, 11, then over the guiding device 12.

Printing is done by a helio machine 13 with a printing unit 14 and a dryer is.

After printing, gumming takes place on the device 16.

The strip 5 for corrugating borne by the roller and coming from the spool-holder 2 goes over the pulley l7 and into the corrugator 18 which positions this strip and gums it on the backing sheet 6 coming from the spool-holder 3. The cylinders 19 apply the reverse of the backing sheet 6 to the microcorrugated strip.

This application is effected with perfect synchronization and positioning strip on to strip, the adjustment of the whole being obtained by the corrugated strip going straight ahead over two photoelectric cells 20, 21, liaising with automatic telecontrols acting directly, at greater or lesser speed, on the adjusting device of the first machine.

The corrugated strips 5 gummed on the reverse side to the backing sheet 6 receive the printed strip 4 on the gummer 16 thus gumming the printed upper side so that the single product 22 is taken up by the cutter 23, then after the making of multiple cuts it is separated by the diver 24 into units ready for assembly.

The advantages and uses of this device for prefabricating preservative wrappings are immediately evident.

A start is made with three grades of paper or primary material, in continuous sheets, i.e. a strip for printing, a surface for corrugating, and a cladding for lining the back.

The strip or sheet for printing, mounted on the twin-element spool-holder 1 allows spools to be changed without interrupting distribution, thanks to the assembly whereby the sheet 4 passes over successive fixed cylinders 7, 8, 9 and mobile cylinders 10, 11 which control the tension of the strip and at the same time constitute a reserve eliminating all stoppages of distribution and releasing the unrolling tensions. Regular working is thus ensured, whatever the possible feed variations may be on one machine in relation to the other.

The guiding device 12 allows the printed strip 4 to be put in place before printing to facilitate the correct positioning when anchoring it. This unit positively controls the tension of the unrolling sheet, i.e. it compensates for the differences in tension which may remain after passing over the cylinder assembly gear, and then adjusts the lining longitudinally in relation to the edge of the sheet. It is then possible, by the triple feed described, to print and fashion the sheet in accordance with a constant reference to one edge.

Printing is done by a known helio process, thanks to the stability of the marker units.

At the same time, the spools 2 distribute the sheet 5 for corrugating over the cylinder 18, while the gumming deflector or pulley 19 joins the backing strip 6 to the shaper. A single'strip is then taken up again an spread out again to receive, on the right side, the printed and dried strip on the gummer 16.

The three strips together are then only cut after the required type of conditioning. This cutting is multiple, and can provide several prepositioned products which are separated by the cutter 24.

This continuous manufacture, by the new application of integers which had not been combined in the same way with a view to the same result, constitutes a new, high-output industrial process.

The gumming of sheets end to end is made possible by the synchronization of the feeds with tension takeup, centering and alternating positioning with the functional units in accordance with the device described. It is specified that speed adjusters make it possible to adapt the linear speed, at which the corrugated paper comes out, to the speed of the printed strip.

Nevertheless, the shapes, dimensions and positioning of the various units may vary within the limits of the equivalents, as may the materials used to make them, without thereby altering the general concept of the invention just described.

lclaim:

1. A machine, for the printing and assembly of a plurality of strips of material for the continuous manufacture of wrapping and packaging material, comprising:

a. means supplying a top layer of material, which includes a spool device to carry a magazine roll of reserve material, and a plurality of spaced cylinders, serving to tension said top layer, and means beyond said cylinders serving to feed and guide said material and compensate for differences in tension;

b. means receiving and printing the face of said top layer material;

c. means supplying an intermediate layer material;

d. means receiving said intermediate layer material and serving to corrugate said material;

e. means supplying a backing layer material;

f. a first gumming device receiving said corrugated intermediate layer material and said backing layer material and serving to unite said materials by adhesive;

g. a second gumming device receiving said printed top layer material and said united intermediate and backing layer materials and serving to assemble all said materials into a multilayer strip; and

h. photoelectric control means between said first and second gumming devices serving to control the speed of feed of the top layer material by guiding means in accordance with the speed of feeding of the united intermediate and back layer materials to the second gumming device.
